The zip_entry_open() function is a built-in function in PHP that is used to open a file in a zip archive. The function returns a handle that can be used to read the contents of the file.


The syntax of the zip_entry_open() function is as follows:

resource zip_entry_open(resource $zip, resource $zip_entry [, string $mode = "r" [, resource $password ]])

Where $zip is the zip handle returned by zip_open(), $zip_entry is the zip_entry handle for the file in the zip archive, $mode is the mode in which to open the file, and $password is the password for encrypted zip archives.

Usage Examples

Let's take a look at a practical example of using zip_entry_open() in PHP.

Example: Opening a File in a Zip Archive

Suppose you have opened a zip archive using the PHP zip functions and want to open a file in the archive. You can use the zip_entry_open() function to do this, like this:

$zip = zip_open("");
$zip_entry = zip_read($zip);

// open the file
$zip_entry_handle = zip_entry_open($zip, $zip_entry, "r");

// read the contents of the file
$file_contents = zip_entry_read($zip_entry_handle, zip_entry_filesize($zip_entry));

// close the file handle

This code opens a zip archive file "" using zip_open(). We then read a file in the archive using zip_read() and open the file using zip_entry_open() with mode "r". The file contents are read using zip_entry_read() and the handle is closed using zip_entry_close().


In this article, we've discussed the PHP zip_entry_open() function and how it can be used to open a file in a zip archive. We've explained what the function does, its syntax, and provided an example of how it can be used in a practical scenario.
